There are some Lexmark color laser printers that are capable of black-only printing w/o the color cartridges installed, unfortunately, the Lexmark C720 printer is not capable of printing with only the black cartridge installed.

Black cartridge error


First, check to see that a toner cartridge is in fact installed.
Open the toner access panel and remove the cartridge.

Check to see if it is indicating that it is empty. If so, replace the toner cartridge and wait for the error message to clear as the machine prepares the new cartridge for printing.

Hello, I want to ask how come i still have a black background. even I already changed the charge roll. My model is Lexmark T430.


Poor development or poorly charged toner particles cause excessive background. This is more noticeable as the print cartridge nears end of life.

Make sure the print cartridge is correctly installed and the high voltage contacts are clean.
If the cartridge is installed correctly and the problem persists, try a new cartridge. The cartridge may be nearing end-of-life.

For further assistance, please contact Lexmark Technical Support

Brand new lexmark printer, toner and cartridges installed, but get error 32 unsupported black cartridge error -tried updating drivers on lexmark site -tried taking cartridge out and reinstaling...


You could find the root cause by performing different steps. One of the easiest methods is that you need to make sure that the plastic protective tape which is usually used on the new black cartridge is off. Usually the user makes this mistake. This mistake might occurs due to absent-mindedness. The reason could also be some distractions which happen while loading the new black ink cartridge.

Error 32 - Unsupported Print Cartridge - Replaced all 4 toner carts and stil getting the error. Could a bad (siezed up) toner cart have caused one (or more) of the rollers in the front cover to shift out...


It looks like having bad (refill??)cartridges. Try original ones. The rollers are there to push the cartridge forwart in the machine on a timed moment to transfer the toner to the belt.

I changed the toner on my Lexmark E250dn and now it has the "!" light on all the time and won't print. It's a new cartridge what is going on?


"!" means error.

Try removing cartridge and installing it again and might be one of the cartridge missing.

Try operating manual. Might helps, there are lots of reason for the error

What parts to be changed for making the printout clear? we have printed the demo page, however the middle par of the paper is quite clear, but not the top and bottom. is it the problem on drum or toner?...


yes probably ur toner is exhausted..
or drum is damp..
or the heater is faulty/defective..
also check the magnetic mesh roller..
do mind for a genuine refill and drum change (if necessary)..
seek a professional supervision esp. ur system admin/vendor....

Lexmark C720 grinding noise & fuser damage


From the site of your Picture, you need a new fuser unit.
The coasting is peeling off... that is not good. And I will bet you get allot of paper jams.

To replace the fusing unit is not hard to do. For the most part taking the covers off the machine and getting them back on is the hard part... Let the fuser unit cool down before you touch it..

Just remember to unplug the machine, Electronic Static Discharge is not good for the Boards in it, touch the metal chassis before you touch the boards if you don’t have a wrist strap) get your self a table and some room to work and take your time.

Take the toner cartridges out
I would do a maintenance kit while I had it apart. (rollers, transfer rollers etc)
Vacuum it out; clean it while you have it open.
(Warning toner and developer is very fine, you might need a vacuum with a micro filter on it, other wise it might go every where)

The service Manual has details on how to do all this. If you follow that you should be ok.
You could try to get all the parts to Fix the fuser unit, but it is easier and faster, cheaper to replace the whole thing. Some places offer a core exchange.

If you need any assistance let me know...

Printer Color problems..


Seriously, buy a new printer. Companies sell toner, not printers! The printer is basically a "freebie" and is a marketing vehicle to sell toner. I tossed my C510 into the dumpster. It had four new toner cartridges. System diagnostics said that everything was at 95% or better. The printer had about 1600 prints on it. The first set of toner cartridges (full at purchase!) printed great. Then, I got dotted lines on clean prints. Or, I would get washed out, yellow tinted print and often, there was no black print. I called a printer repair shop and they laughed and told me to chuck the printer - they were suprised it lasted through the first set of cartridges. Lexmark literally "ignored me to death."

I will NEVER buy another Lexmark. The Brother and HP color lazers are probably the best bet. I have two HP B&W's that are paper pumps - an old 4V and a 6MP. The sad part is that I paid a bit more for the Lexmark than the competing HP. You live and then you learn!
